Flux is a substance that chemically combines with gangue (earthy impurities) that may still be present in the calcinated or roasted ore to form easily fusible material called slag. Fluxes are classified into two types: basic fluxes and acidic fluxes. The type of flux used is determined by the nature of the impurities present in the "ore."

Suppose a point charge +q rests in space. Consider a sphere of radius r that encloses the charge such that it lies at the center of the sphere. From the symmetry of the situation, it is evident that the electric field will be constant on the surface and directed radially outward. Applying Gauss’ law, we get The above equation gives the electric fie...
Consider an infinite distribution of charge like a line charge with charge density λ. Imagine a cylindrical surface of radius r and height hthat encloses the line charge, located at its axis. From the symmetry of the situation, it is clear that the electric field will be equal at every point on the surface and have a radial component only. Tangenti...
Consider an infinite plane sheet with charge density σ. Now, consider a cylindrical surface that encloses the plane. The plane cuts the imaginary cylinder at its center. The symmetry of the situation dictates that the electric field must be perpendicular to the cross-section of the cylinder and the plane. Therefore, for the top surface And, for the...
- A uniform electric field with a magnitude of $E=400\,{\rm N/C}$ incident on a plane with a surface of area $A=10\,{\rm m^2}$ and makes an angle of $\theta=30^\circ$ with it.
- Find the electric flux through the surface with sides of $15\,{\rm cm}\times 15\,{\rm cm}$ positioned in a uniform electric field of $E=150\,\rm N/C$ as shown in the figure below.
- A square surface with sides of $\rm 1 m \times 1 m$ located over the $xy$-plane, where a constant electric field with a magnitude of $200\,{\rm N\cdot m^2/C}$ presents.
- In the figure below, a flat surface of sides $\rm 10\, cm \times 50\, cm$ is positioned in the presence of a uniform electric field of unknown strength.
Electric flux measures how much the electric field 'flows' through an area. The flow is imaginary & calculated as the product of field strength & area component perpendicular to the field. Created by Mahesh Shenoy.
May 3, 2023 · In each diffusion reaction (heat flow, for example, is also a diffusion process), the flux (of matter, heat, electricity, etc.) follows the general relation: Flux = (conductivity) x (driving force)
In the following, a number of solved examples of electric flux are presented. More simple problems including flux of uniform or non-uniform electric fields are also provided. Example (1): electric flux through a cylinder.
